Planting Cestrum

We recommend planting in spring.

Grow it in the ground if the climate is relatively warm. If not, plant in garden boxes with soil mix to bring them indoors in winter.

Propagation is through cuttings in spring on semi-hardened sprigs.

For Cestrum from seed, favor sowing in trays in spring.

Pruning cestrum

It doesn’t need any pruning. However, if you want to control its size or shape, go ahead and prune at the end of winter (make sure the last frost date has passed).

More severe pruning every 3 years will trigger a fresh bout of more vigorous blooming. In addition, branches will grow more dense and lush overall.
